A study compared the drug use of 288 randomly selected high school seniors exposed to a drug education program (DARE) and 335 randomly selected high school seniors who were not exposed to such a program. Data for marijuana use are given in the accompanying table.
| number who use marijuana | ||
|---|---|---|
| exposed to DARE | 288 | 141 |
| not exposed to DARE | 335 | 181 |
At the 5% significance level, is there convincing evidence that the proportion using marijuana is lower for students exposed to the DARE program?
Round these answers to two places after the decimal:
Test-statistic = (to two places after the decimal)
P-value = (to four places after the decimal)
There sufficient evidence to conclude that the proportion of students using marijuana is lower for students exposed to the DARE program.
